FNELHVIATIC PAINTING APPARATUS. f

' SPECIFICATION forming art of Letters Patent No. 577,496, dated February 23, Application iiled March 20,1896. Serial No. 684,164. (No model.)

To all whom it may concern.-

Be it known'that'we, ROUGH SEDGE WALL- WORK and ARTHUR UOLLINGS WELLS, sub-' jects of the Queen of England, residing at Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Pneumatic Painting Apparatus; and we do hereby declare the followand exact description ing to be a full, clear, of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to lettersof reference marked thereon, which forms a part of this specification.

Our invention has relation .to apparatus for coating the surfaces of small articles mechanicallywith paint and other like more or less fluid or viscous protecting agents; and it has for its object'an apparatus of simple construction, easilyv manipulated, and of great efiiciency and practical utility.

In the accompanying drawing we have shown our improved apparatus partly in elevation and partly in section.

Broadly speaking, our said apparatus com-,

' prises 'an ejector spraying-nozzle provided with a passage for air and with a passage for paint, a source of compressed-air supply and a source of paintsupply respectively connected with said passages for air and paint,

a receiver for the surplus paint, and means for exhaustingnoxious vapors from said receiver.

In the drawing we have shown as an example a storage-chamber for compressed air from which the air-compressor and its driving-shaft are supported, and we have also shown a paint-receptacle supported from the pipe that supplies air under pressure to the passage for such in the ejector spraying-nozzle, but we do not desire to limit our invention thereto, as any other suitable source of compressed-air supply may be made use of and the paint-receptacle may be located at any suitable point,'so as to supply paint to of the cylinder I such air as is contained in the cylinder below the passage for such in the ejector sprayingnozzle. Y

In the drawing, S indicates a standard which is hollow or chambered and serves as a storage-chamber for the air forced into the same. 0 indicates the compressor-cylinder on the base of the standard S and in communication therewith by a suitable passage, any usual and well-known means being provided, as a check-valve, to prevent air from flowing from the standard back to the cylinder, the air-forcing devices being, as usual, of such a nature as to allow free passage of air into the cylinder below its piston or ram on the up.- stroke and prevent such air from passing out on the downstroke, whereby its piston is forced into-the standard S.

Inasmuch as the appliances for supplying air under pressure to the ejector sprayingnozzle do not form a part of this invention we have deemed it unnecessary to illustrate the same in detail, especially as this omission can in no manner interfere with such a thorough understanding of our invention as will enable others to make and use the same.

At'its upper end the standard S is provided with a bearing for a driving-shaft S, that "m ay be set in motion from any suitable prime motor or by hand. To these ends the shaft carries the usual fastandloose belt-pulleys 19 1) and a crank-handle h. Said shaft also carries a fly-wheel w, to the Wrist-pin of which is journaled the piston-rod R of the air-compressor, and saidstandard has a suitable coupling branch b, provided with a pressuregage g,'and said branch is or may beprovided with a blow-0E cock.

' 13 indicates a bench, to which is secured a bearing 11 for the passage of a rigid air-pipe P, that is connected with ble pipe or hose P, the said pipe P being adjustable vertically in its hearing by means of a set-screw b.

The rigid air-pipe Pis bent at right angles the coupling branch b of standard S, preferably by means of a fiexitom of a paint-receptacle R, that is provided with a discharge-spout r, in which is fitted a suitable controlling valve or cock '1';

To the outlet end of the air-pipe P is secured an ejector-nozzle N, consisting of a 1101- low open-ended casting terminating in an airnozzle N, to which is screwed a cup-shaped paint-nozzle N into which-the air-nozzle N projects.

Upon the bench Bis arranged a collecting vessel D, the mouth d of which is contracted and serves as a seat fora conical or tapering open-ended collecting-funnel E, that gathers such paint as may run ofi' the article being coated and held in the spray of paint between said funnel E and the ejector spraying-nozzle N, said funnel extending near to the bottom of the vessel D, wherebya space is left around the funnel below its seat.

above its bottom and above the lower open end of funnel E, said port being connected, preferably by mea'ns of a flexible pipe P with any suitable exhaust apparatus, as an exhaust-fan, (not shown,) whereby noxious gases may be drawn from the vessel into the atmosphere-outside of the room or shop in which the bench is located.

As shown in the drawing, the upper open end of the spraying-nozzle N is normally closed by a screw-plug 71), so that access can be had to the interior of the nozzle N as well as to the interior of the nozzle N when this is required. I

From the description of the apparatus its operation will be readily understood, and does, therefore, not need to be specifically described. 4

Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent, is-

1. An apparatus such as described, comprising a spraying device consisting of an airnozzle, means for supplying air under pressure to said nozzle, a cup-shaped paint-nozzle surrounding said air-nozzle, and a receptacle for paint adapted to supply paint to said cupshaped noz'zle, for the purpose set forth.

2. An apparatus such as described, comprising a spraying device consisting of an airnozzle and an air-supply pipe connect-ed therewith, a cup-shaped paint-nozzle surrounding said air-nozzle, and a receptacle for paint on the air-pipe and adapted to supply paint to said cup-shaped nozzle, for the purpose set.
